If cost is a major factor and you want a high-resolution experience with decent gaming performance and good productivity, the Asus would be a sensible choice. However, if you're willing to invest more for a superior color contrast, deeper blacks, and a more immersive ultrawide gaming and media experience, the Dell Alienware's QD-OLED display offers distinct advantages, especially in HDR content. It won't offer the same sharpness in text clarity due to a lower pixel density but excels in image quality and color reproduction. For competitive gaming, both are adequate, but the Dell's higher refresh rate and response time give it an edge. Give Feedback

"The Asus TUF Gaming VG28UQL1A is, in many ways, a great 4K gaming monitor. It has a sharp, accurate image with good contrast and excellent motion clarity. Luminance uniformity is its only weakness. The monitor’s $799 MSRP is relatively affordable for a 4K HDMI 2.1 monitor, as well."

"It may seem like a minor tweak, but the addition of a glossy anti-glare coating makes all the difference. It really lets the OLED panel rip. That this revised "F" model is also cheaper than the OG Alienware OLED and the similarly glossy Philips competition seals the deal. This is our new favourite among the OLED monitor massive."
